The article states that usability is declining, the arguments to back that up are: things are somewhat inconsistent and I don't like [some UI patterns].
My point is that the claim is wrong, and the arguments don't support it and have little to do with usability.
This follows from a misconception that usability, UI, and user experience are the same thing, which is really showing a lack of understanding of what they actually are.
I write my comments in the hope that people will actually look into these topics more deeply as they are quite interesting and often require setting aside the preferences, gut instinct, and pet peeves this article is filled with.
